Lightstrike is a sensory defect that mainly affects white wines that have been exposed to ultraviolet light between the 370 and 450nm wavelenghts and is caused by the degradation of riboflavin and the formation of sulfur compounds.

This defect manifests itself through colour and aroma loss and the presence of sulfur, onion, garlic or cooked cabbage odours.

In the first video seminar Davide Camoni offers an introduction to this subject, with a rapid analysis of the sensory descriptors and the thermodynamic and kinetic models that describe this defect as well as some options to prevent it.

After, Jordi Encinas Herrando presents the research of his team in three main lines of study: the influence of the yeast on the presence of riboflavin in the wine, understanding the degradation kinetics of this molecule when it is exposed to light and finally the reduction of its concentration using specific fining treatments.

To conclude, Maria Manara shows the practical applications of these studies in the winery by describing some possible predictive factors and the tools available to winemakers in order to, limit the production of riboflavin, reduce its content by fining, and protect the wine during the bottling phase by using substances or adjunts that have a protective action with regards to this defect.


The seminar reproduced in this video was presented at the 9th edition of Enoforum (Vicenza, Italy, 5-7 May 2015). Seminar sponsored by Dal Cin
